0024307: TKOpenGl - efficient culling of large number of presentations

Browse Source 
Implement SAT intersection tests and frustum culling algorithm using BVH trees.

New Draw command vfrustumculling to manage frustum culling.
Add test cases bugs/vis/bug24307_1 and bugs/vis/bug24307_2.
Remove CALL_DEF_BOUNDBOX and CALL_DEF_BOUNDS.
